Be it knownthat I. ROBERT C. RUSSELL,

a citizen of the United States, and a resin-J dent of Pittsburgh, in thecounty of Allegheny and Sta-te of Pennsylvania, have in-` ventedcertainnew and useful Improve-I- ments in Card Indexes;` andI do herebydeclare the following to be a full, clear, and

exact description vofthe invention, such as will enable others skilledin the art to 'which it appertains to make and use the saine.

This invention relates to improvements in card indexes of the visibletype and has for its object the provision of index ele- F ments whichshall be so constructed that they will be properly supported, one byanother in uniform spaced relation so asto provide exposed datareceiving portions of uniform area throughoutl theseries of indexelements and so that all of the index elements shall be retainednormally in proper position in a holder but capable of being moved orremoved as may be required.

TvVith this and other objects in view, the invention consists in certainnovel features as hereinafter set forth and pointed out in the claims.

In the accompanying drawings,

Figure l is a `face view showing a card index illustrating myimprovements.

Figure is a rear'view' in perspective of one of the index elements.

Figure 3 is a rear face view showing several index elements, and

Figure 4 is a fragmentary sectional view on the line 4 4 of Figure l.

The index elements l are supported, mov'- ably and removably by a holder2,-the. latter having shoulders 3 at its respective end portions andprovided at its side portions with f flanges 4 which overlie portions ofthebot- Y tom of the holder and provide guide-waysA 5 which receive theends of the cards or index elements 1. i Y

Each index element [l may be made of cardboard or other suitableflexible material.

Each card or element l is slit near its-re` spective ends on diagonalconvergent lines,

forming inwardly projecting, horizontal approximately V-shaped tongues 6and the apices of these tongues are preferably Vrounded as shownV at 7.The material of the card between the base portion of Athe respectivetongues is bent rearwardly and upwardly, forming a resilient tongue 8Vand ltions of the several index elements will have uniform areas.

. Having fully described my invention what I claim as Vnew and desire tosecure by Letters-Patent, is: V

l. Ina cardl index, an index element having inwardlyvprojecting tonguesnear its` respective ends andV the material between the base portions ofsaid tongues being bentY rearwardly and upwardly forming a resilienttongue providing a pocket.
